According to the Japanese official baseball rule, the use of the wooden bat is required in professional baseball, non-professional teams and university league. Recently, the domestic wood materials for baseball bat dried up and the bat with the import wood from North America is used now in Japan. On the other hand, the bamboo bat used for training conventionally has characteristics such as abundant material and cheap, but is not used in the game because rebound performance, strength and rigidity are small compared with wooden bats. Therefore, in this study, the some bamboo composite bat composed by hickory and maple was made for the experiment, and the rebounding performance investigated by the ball collision test in the high speed using the air cannon system. As a result, the rebounding performance of the bamboo composite bat that is equal to the conventional wooden bat was obtained.
